ART. 28 REVISION OF DISONYCHA NORTH OF MEXICO BLAKE 35 



beetles are much briohter in coloring. Casey's beetles now have the 

 usual appearance of dried museum specimens of this species. 



14. DISONYCHA FIGURATA Jacoby 



Plate 3, Figitbe 15 



Disnnycha figurata Jacohy, r>ioi. Centr. Amer., vol. 6, pt. 1, p. 814, 1884 (type 

 not designated; Mexico to Panama). 



Description. — Broadly oval, feebly shining, pale yellow; prothorax 

 with 2, rarely 4 dark spots anteriorlj^ ; elytra with usually indistinct 

 sutural, median, and submarginal vittae, occasionally these vittae 

 dark brown and well marked. Head with interocular space more 

 than half width of head ; interantennal area broad, scarcely carinate, 

 a group of punctures about fovea on each side near eye ; head smooth, 

 shining and entirely pale except for the brown labrum and occasion- 

 ally slightly darkened frontal tubercles. Antennae piceous, fourth 

 joint longer than third or fifth. Prothorax less than twice as broad 

 as long, convex, narrowed anteriorly with slightly arcuate sides; 

 shining, indistinctly and sparsely punctate; pale with 2 anterior 

 dark spots, occasionally, in darker specimens, with 4 spots and a trace 

 of a median line. Scutellum brownish. Elytra oval, somewhat con- 

 vex, with humeri not prominent; surface shallowly, closely, and 

 rather indistinctly punctate; pale yellow with usually indistinct 

 and narrow sutural, median, and submarginal vittae, the submar- 

 ginal and sutural vittae tending to unite at apex; in darker speci- 

 mens the vittae sometimes stronger and brownish. Body beneath 

 pale with middle of metasternum and occasionally middle of abdo- 

 men dark, a streak, sometimes a darkened area, on femora, and the 

 apex of tibiae and tarsi dark. Length, 6.2 to 7 mm; width, 3.2 to 

 3.5 mm. 



Type locality. — Not designated; the following localities given: 

 Mexico (Ventanas, Cerro de Plumas, Oaxaca, Juquila, Cordova, 

 Playa Vicente, Tuxtla, Capulalpam, Guanajuato) ; Guatemala (Cap- 

 etillo, Duenas, Chacoj) ; Panama (Bugaba). 



Distribution. — Nevada (Hot Springs) ; Arizona (Nogales, Pata- 

 gonia, Santa Rita Mountains). Mexico to Panama. 



Food plant. — Unknown. 



R-emarks. — This species, described by Jacoby from Mexico, Guate- 

 mala, and Panama, has been collected in the United States in Nevada 

 and Arizona. It is remarkable on account of its pale and ill-defined 

 elytral vittae, often so indistinct that the elytra appear entirely 

 pale yellow-brow^n. Occasionally, in a darker specimen, the vittae 

 are distinct enough to make the species easily confused with latifrons 

 or even fuviata., but the paler undersurface and the shape of the 

 aedeagus distinguish these darker forms. It is quite distinct from 

 any other North American species, in spite of Jacoby's statement
